5. Power Supply
Connect the board to a power supply with the following characteristics.
CN7
1pin +5V
2pin 0V
3pin N.C.
4pin N.C.
6. Precautions
The following measures are required to input a clock signal to the CLKIN pin.
•
Mount
CRU1.
•
Remove C2, C3, R4, and R18.
•
Connect pin XI via a jumper to GND. Leave pin XO open.
The input width to the CLKIN pin must be of the same voltage as CPU I/F Level designated with JP3.
However, for reasons related to the power supply to CRU1, note that this will be 1.8 V for this board.
